video/ audio playing automatically when swiping through facebook news feed

Hi again
Has anyone else noticed when you open facebook and flick right to go through your news feed that some audio/video automatically plays on some peoples posts until you swipe on to the next. I am not double clicking into their post or anything, just flicking through in the main news feed. Is there a way to get rid of this? You can't listen to voice over read while audio automatically plays when you arrive on it. It's maddening.
